I'm not trying to convince anyone that that isn't maidenhair fern, but I used to know this guy that called it parachute fern. He also called black cohosh \"pointer\" and that was all he called it. He couldn't tell you the first thing about goldenseal, but probably dug more yellowroot than anybody I've ever met. I don't pretend to know for sure, but I think that in some circles parachute fern is what this plant is called. If there is some other fern called parachute fern please post a picture. I will never know enough about the great outdoors.
